The purpose of this study was to systematically investigate the performance of different radiographic views in the identification of scaphoid fractures in children.

This case-control study compared 4-view radiographic examinations of the wrist between children with scaphoid fracture and age- and sex-matched children without fractures performed between January 2008 and July 2019. After randomization, each examination was reviewed 3 times, at least 1week apart, first using each view separately and later using multiple views without (3-view) and with the posteroanterior (PA) scaphoid view (4-view), to determine the presence or absence of a scaphoid fracture. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated with inter-rater agreement.

The study group of 58 children (48 boys and 10 girls; mean age 13.1 ± 2.1years) included 29 with scaphoid fractures (8 corner, 9 distal pole, 10 waist, and 2 proximal pole) and 29 without fractures. Multiple views had higher sensitivity (3-view, 93.0%; 4-view, 96.5%) for fracture identification when compared to individual views (41.0-89.6%). The oblique view was 100% specific for the identification of a scaphoid fracture, but it lacked sensitivity. The PA scaphoid view had the highest sensitivity (89.6%) and NPV (90%) when compared to other individual views and its inclusion in the 4-view examinations produced the highest inter-rater agreement (93%, κ= 0.86).

Multiple radiographic views of the wrist with the inclusion of a PA scaphoid view (4-view) produced the highest sensitivity, NPV, and inter-rater agreement for the identification of a scaphoid fracture in children.

However, study on IS genetics by whole mitochondrial genome sequencing has not been extensively explored. Therefore, a two-stage study was designed to explore the relationship between the whole mitochondrial genome variants and IS. In the first stage, whole mitochondrial genomes of 52 IS patients and 55 controls were sequenced by next-generation sequencing. Fifty-three mtDNA mutation sites which may be related to the pathogenesis of IS were discovered. Nine unreported mtDNA variation sites were found for the first time. In the second larger Chinese cohort, we confirmed that m.T195C and m.T12338C in the mitochondrial D-loop region were the protective factors of IS, especially m.T195C and m.C311T in the LAA subtype. In conclusion, our study provided population genetic information and a reference for IS-relevant research, with wide applications in diagnosis, therapeutic treatments and prediction of IS.Nigrostriatal pathway disturbance is one of the major pathogenic factors in Alzheimer's disease (AD). Dopaminergic neuron dysfunction results in bradykinesia and akinesia (inability to initiate movement), indicating a significant risk factor for substantia nigra pars compacta lesions. Furthermore, the nicotinamide adenine dinucleotide (NAD+) is associated with Aβ toxicity decline in AD therapy. Nicotinamide mononucleotide adenylyltransferase 1 (Nmnat1) is an essential enzyme that preserves normal neuronal function and protects neurons from insult. This study aimed to investigate the potential therapeutic effects of Nmnat1 and its underlying mechanisms in a triple-transgenic mouse model of AD (3xTgAD). Results showed that Nmnat1 improved the substantial behavioral measures of cognitive impairments compared with the 3xTgAD control. Additionally, Nmnat1 overexpression significantly increased tyrosine hydroxylase-positive neurons and anti-apoptotic protein Bcl2 and caspase-3 expression levels in 3xTgAD mice. Nmnat1 also effectively controlled SOD1 activation. In conclusion, Nmnat1 substantially decreases multiple AD-associated pathological characteristics at least partially by the increase of caspase-3 activation.Migraine is a common neurovascular condition. This disorder has a complex genetic background. Several single-nucleotide polymorphisms (SNPs) or mutations within genes regulating glutamatergic neurotransmission, cortical excitability, ion channels, and solute carriers have been associated with polygenic and monogenic forms of migraine. SNPs within ACE, DBH, TRPM8, COMT, GABRQ, CALCA, TRPV1, and other genes have been reported to affect the risk of migraine or the associated clinical parameters. The distribution of some HLA alleles within the HLA-DRB1, HLA-DR2, HLA-B, and HLA-C regions have also been found to differ between migraineurs and healthy subjects. In addition, certain mitochondrial DNA changes and polymorphisms in this region have been shown to increase the risk of migraine. A few functional studies have investigated the molecular mechanisms contributing to these genetic factors in the development of migraine. Here we review studies evaluating the role of genetic polymorphisms and mRNA/miRNA dysregulation in migraine.Clear cytoplasm is a major characteristic feature of most malignant renal neoplasms. Benign clear cells in the renal parenchyma, usually histiocytes, can occasionally be found, but they are infrequently of an epithelial nature. We report histological, immunohistochemical, ultrastructural, and cytogenomic features of clear epithelial cell clusters incidentally found in four kidney specimens. Multiple microscopic clear cell clusters were present in the cortex, often in subcapsular location. They were composed of large epithelial cells with strikingly clear cytoplasm, without nuclear atypia, arranged in solid nests, and some tubules with narrow lumina. Immunohistochemically, they were positive for AE1AE3, PAX 8, EMA, kidney-specific cadherin, cytokeratin 7, E cadherin, and CD117, with focal immunoreactivity for CD10. Carbonic anhydrase IX, vimentin, and markers related to apoptosis and proliferation were negative. Ultrastructurally, the cytoplasms were enlarged and poor in organelles, showing ballooning degeneration. Array comparative genomic hybridization showed no chromosomal gains or losses. Clear cell clusters constitute a rare finding in the kidney and must be differentiated from benign lesions (ectopic adrenal tissue, osmotic tubulopathy, histiocytic clusters, renal adenomas) and renal cell carcinomas. Clear cell clusters appear to be generated from "endocrine-type" atrophic tubules whose cells are enlarged due to intracellular oedema. Immunohistochemistry shows a distal nephron phenotype with a limited expression of a proximal marker, CD10. Coexisting chronic renal disease or ischemic conditions seem to be related to the development of clear cell clusters. Pathological, ultrastructural, and cytogenomic features do not support a preneoplastic nature of this lesion, at least in the cases studied here.The effect of dietary supplementation of Crassocephalum crepidioides leaf powder (CCLP) in comparison with oxytetracycline and butylated hydroxyanisole (BHA) on growth, caecal microbiota, immune status, blood chemistry, carcass traits, meat quality, and oxidative stability in broiler chickens was evaluated. Two hundred and eighty 1-day-old Arbor acre chicks were randomly assigned to a basal diet containing either no additive (control, CON), 400 ppm oxytetracycline + 150 ppm BHA (ANTIBIOX), 1000 ppm CCLP (CCLP-1), or 2000 ppm CCLP (CCLP-2) for 42 days. Each dietary group had seven replicates with ten birds per replicate. Supplemented birds had higher (P  less then  0.05) feed efficiency, hemoglobin, and hematocrit compared with the CON birds. Diet did not affect feed intake, body weight gain, splenic interleukin-1β, interleukin-6, interleukin-10, and serum IgM. The CCLP-2 birds had lower (P  less then  0.05) serum total and LDL cholesterol than did birds fed other treatments. Salmonella spp. and Escherichia coli counts and serum IgG were higher in the CON birds than in the supplemented birds. The ANTIBIOX birds had lower (P  less then  0.05) Lactobacillus spp. count, and higher (P  less then  0.05) E. coli count compared with the CCLP-supplemented birds. Carcass, muscle pH, and cook loss were not affected by diet. The CON breast meat had higher drip loss and lower redness than did the breast meat of the supplemented birds. Carbonyl content and TBARS value in the thigh and breast meat of the supplemented birds were lower (P  less then  0.05) than those of the CON birds. These results infer that CCLP exhibited antioxidant and antimicrobial properties that were comparable to those of BHA and oxytetracycline in the diet of broiler chickens.In this commentary, I discuss the contribution of the target article (Sulaeman et al. 2020) and suggest further study in terms of research on psychosocial issues of people with physical disabilities. NHWD870 The authors of the target article qualitatively analyzed the disability-related experiences of people with oligodactyly in a rural village in Indonesia, employing the theories of stigma (Goffman 1963) and illness narrative (Kleinmann 1988). First, the authors effectively found the meanings of the participants' minor daily experiences by focusing on their physical organ abnormalities. Oligodactyly is visible and mild, rather than other disabilities such as spinal cord injury. A detailed analysis is required to clarify the effect of disability. The authors found that their bodily differences and disorders had multifaceted meanings rather than negative ones only. Another finding was that "God" was referred to as a mediator connecting diverse meanings and places revealing uncertain experiences. Additionally, I discuss that the visibility of oligodactyly depends on the context, and that visible or invisible dichotomy is not suitable for studying psychosocial issues. I argue that people with mild disabilities face the dilemma of disclosing their condition to others. My suggestion for further study is to examine the development of disability meaning from a long-term perspective to elucidate the meaning's evolution through the participant's interaction with family, community, and area outside that village. The concept of narratives in cultural psychology, such as Bruner (2002)'s narrative mode of thinking, was useful; narrative was interfering with the future, past, and present (Valsiner 2007).Autism is a complex neurodevelopmental broad-spectrum disorder characterized by social interaction, and aberrant restrictive and repetitive behavior. The complex pathophysiology and unexplored drug targets make it difficult to standardize and validate the animal models of autism. The review was purposed for determining the benefits of younger animal models over adult models of autism. Similarly, animal models with respect to age, sex, body weight, number of animals used, along with autism inducing agents have been reviewed in this article. The differentiation of behavioral parameters has shown the benefits in the selection of younger animal models. Thus, we conclude that young and adolescence animal models of autism will be supporting for early detection and interventions with significant results.
